@Manoj Bobade Thanks for reaching out. As per our Product group, customizing tooltips for visuals/charts rendered from Kusto queries is not supported out of the box as of today. However, this is in our backlog as there have been similar requests from other customers in the past.
While there aren't any timelines we can share on the ETA at this point, please watch out for any new announcements/updates on Azure Updates/Azure Blog.
Hope this helps. Do let us know if you have further questions.
